I bought a pair of CF front splitters and plan on installing them this weekend. I am concerned about scratching the paint while installing this part. Inner side of the part is rough and I wanted to see what other people have done to prevent any possible damages to the bumper/paint. I was thinking of either applying vinyl to smooth out the surface or applying plasti dip.

Did yours have a similar non finished surface? I feel like the roughness will scratch the paint when slipping it on.

I sanded it, painted with 3 coats of primer, then followed by 3 coats of clear. This got the inside real smooth. Went to install the part and it doesn't fit at all. Not even close. It that to a point where I felt the stress of poor fitment was going to crack and break the eBay CF splitters.
